Filed: 1994-05-09
Abstract: PURPOSE:To provide an infrared spatial transmission system for easily providing spatial transmission (so-called wireless transmission) while utilizing an RF output with which an audio visual equipment is most generally provided. CONSTITUTION:The RF signal of a video dedicated channel is outputted from a video equipment 1. Then, that RF signal is frequency-converted into a low frequency so as to be transmitted by an infrared LED or a light receiving element by a frequency converter 3 and amplified. Then, the infrared light with intensity corresponding to the voltage of the amplified signal is radiated from a light emitting circuit 4 to a receiver 5. At the receiver 5, the infrared light arriving at a light receiving circuit 6 is converted into an electric signal by the light receiving circuit 6 and amplified by a preamplifier 7. Then, that signal is frequency-converted into a high frequency by a frequency converter 8 again amplified by an RF amplifier 9, made into low impedance and outputted to a television 10.

Title: Channel selection device
Inventor: FUJIMOTO ISAO
IPC: H03J3/18
Filed: 1980-07-10
Abstract: PURPOSE:To regulate the lower limit of a receivable frequency range adequately only by modifying a conventional device slightly, by applying a regulation voltage only when a band which should be regulated is selected. CONSTITUTION:A switching part 8 consists of switching transistors TR81 and 82, and the base end of the TR82 is connected to a switching terminal Bh for the VHF high band which should be regulated. Consequently, the TR81 turns on only during the reception of the VHF high band to extract a lower-limit regulation voltage Vhl. This voltage Vhl is further applied to the tuning-voltage application terminal 24 of a tuner 2 via a switching diode 9. Therefore, while the output voltage of a channel selection part 4 drops below the voltage Vhl, the diode 9 turns on to hold the tuning voltage at the voltage Vhl, thereby regulating the range of a lower-limit receivable frequency.

Title: Memory device
Inventor: YAMAGA MITSUHIRO
IPC: G11C5/14
Filed: 1978-08-09
Abstract: PURPOSE:To obtain a memory device which can make the best use of the performance of the memory element by detecting the temperature within the memory device via the sensor element and then controlling the cycle time based on the detection output. CONSTITUTION:Sensor element 1 is turned on with increment of the temperature with the output turned to the low level, and the reset timing of flip-flop (FF) 9 is carried out with TX+alpha of a slower phase than TX. This extends the cycle time of the memory device. In other words, the temperature increase of the dynamic semiconductor memory element (RAM) is affected by the access frequency within a fixed time. And the temperature of RAM increases as the access frequency increases, and accordingly the access frequency can be limited by detecting the temperature increase and then extending the cycle time. As a result, the temperature of RAM can be lowered down without intensifying the function of the cooling mechanism especially. In case the temperature is low within the memory device, the cycle  time is accelerated to enhance the performance of RAM.
